[Wrong choice of controller] Arduino is awesome

Overview

This project is based on the atmega328pb-au USB-arduino which is super awesome

Tip: The USB thickness is about 2.4mm, but if it is too thick, it will cost extra, so it is recommended to make it 2mm and then add solder to thicken it.

The board comes with USB. Yes, it uses PCB for USB and comes with a serial port chip. Although it is small, it has all the functions it should have. There are 3 rows of pins on the board, each row has 5 holes. , including:

1 x TX RX serial port (can also be used as normal IO, but it must be unplugged before uploading the program otherwise the upload will fail)

1 x IIC Communication

3 x ADC (IIC interface is also ADC, A4, A5)

4 x PWM

Basic servos and I2C devices can be driven. When there is no I2C device, the I2C interface can be used as an ADC. It can be said that even though it is small, it has all the internal organs!

After the board is soldered, the corresponding BL (BootLoader) tutorial will be published. Everyone is welcome to leave a message for areas that need improvement!
